SPECIFICATION forming part of Letters Patent N o. 573,833, dated December 22, 1896.

To @ZZ whom it may concern.-

Beit known that I, THOMAS I-I. SPRINGER, a citizen of the United States, residing at Philadelphia, in the county` of PhiladelplfiiaJ and State of Pennsylvania, have invented certain new and useful Improvements in Scum i and Dirt Arresters for Centrifugallliachines for Separating Liquids, of which the follow` ing is a specification.

" centrifugal machines orseparating liquids. The object is to produce a device by which the outlet or outlets of a separator-bowl will beat all times maintained clear and unob-` I 5 structed and the contained lforeign substances of the liquid prevented from accumulating at these points.

` With this obj ect in view the invention con sists in certain novel construction and arzo rangement of parts, which will be hereinaftei1 v fully described, and pointed out in the claim.

In the accompanying drawings, forming part of this specification, similar letters of reference indicate corresponding` parts in the 2 5 several views, in whichwh Figure 1 is a view of a section of a sepa` rator-bowlwith the improvements applied Fig. 2 is a sectional view on the line oc 0c of Fig. 1. 3o of the bowl mounted.

` In the drawings, A represents the bowl of a centrifugal machine such as is now com` `monly employed for separating liquids, the machine illustrated being particularly adapt- 3 5 ed `for skimming milk.

f wholly or partially closing the opening.

The invention relates to improvements in Fig. 3 is a transversesectional view partitions or wings. This opening serves as the outlet for the skim-milk, and heretofore the capacityof machines of this class has been greatly reduced by the deposit of foreign substance contained in the milk accui mulating rapidly at the outlet and either This reduction in the size of the outlet often resulted in bending and forcing the skim-ring out of position by the action of the milk in forcing a passage.

B represents the arrester, which is preferably of metal inthe form of a ring or ange, and is designed to be secured around the inner wall of the -bowl at a suitable distance from the outlet.

It is essential that the width of the ring be as great, if not greater, than the i andwhereby an annular passage is formed between the ring and the bowl and a metallic ring secured to the wall of the bowl below the skim-ring at such a distance as to prevent the passage of dirt andthe like, as and for the purpose described.

In testimony whereof I have hereunto af- :fixed my signature in the presence of two subscribing witnesses.
